In general, when a relatively long crop such as a ginger is sown in a vegetated state, there are a method of facing and additional trimming. Already known mowing cuts the lying crops from the rear side, so after cutting by the first cutting device 3 of the present plan (the foliage at the time of cutting is above the clamping part at the front side of the vehicle body 4 The leaflet transport device 5 is at a high position and is separated from the end of the pulling transport device 2 before inheriting, and the timing of inheritance becomes a problem.

以下、実施例を説明する。
まず、上部搬送装置３６は、図１３、図１４に示すように、左右一対の搬送ベルト３６ａ，３６ａを前記引上げ搬送装置２の上方において、前後方向に配置し、始端部を前部の前記誘導ベルト１ａ，１ａのプーリ２１，２１の軸に連結した支持杆３７で支持し、終端部を車体４の後左側部、前記排葉搬送装置５の終端部の位置まで延長して構成している。実施例は、左右一対の搬送ベルト３６ａ，３６ａを、始端部分において、誘導案内装置１の後部上方で左右両側から内側に案内できる配置にして引上げ搬送装置２の上方では左右両側から緩く搬送案内ができる程度に設け、後部では排葉搬送装置５に代えて挟持搬送機能を持たせて構成し、切断後の茎葉を引上げ搬送装置２の終端部から適確に受け継ぎ中吊状態に挟持して搬送ができるものとしている。 Examples will be described below.
First, as shown in FIG. 13 and FIG. 14, the upper transport device 36 has a pair of left and right transport belts 36 a and 36 a disposed in the front-rear direction above the pulling transport device 2, and a leading end is the front guide. The belt is supported by a support rod 37 connected to the shafts of the pulleys 21 and 21 of the belts 1 a and 1 a, and the end portion is extended to the position of the rear left side of the vehicle body 4 and the end portion of the leaf transport device 5. . In the embodiment, the pair of left and right transport belts 36a, 36a are arranged so that they can be guided inward from the left and right sides above the rear portion of the guiding guide device 1 at the starting end portion, and the transport guide is loosely guided from the left and right sides above the pulling transport device 2. Provided as much as possible, the rear part is configured to have a holding and conveying function instead of the leaf discharging and conveying device 5, and the cut foliage is properly pinched from the terminal end of the conveying device 2 and held in a suspended state while being transferred. It is supposed to be possible.

このように構成すると、上部搬送装置３６は、車体４の進行方向に対して前方側に倒伏している生姜の茎葉を左右の搬送ベルト３６ａ，３６ａで適確に中央の搬送通路側に案内して下側を引上げ搬送装置２に供給することができる。そして、上部搬送装置３６は、そのまま搬送するが、下側の引上げ搬送装置２が茎葉を挟持して上側に引上げ作用をするが、これを邪魔することなく緩い接触状態で案内搬送することができる。 If comprised in this way, the upper conveying apparatus 36 will guide the ginger foliage lying down ahead with respect to the advancing direction of the vehicle body 4 to the central conveying path side with the right and left conveying belts 36a, 36a. The lower side can be supplied to the pulling and conveying device 2. The upper conveying device 36 conveys the material as it is, but the lower pulling and conveying device 2 sandwiches the foliage and raises the upper side. However, it can be guided and conveyed in a loose contact state without interfering with this. .

なお、上部搬送装置３６は、図１５に示すように、搬送距離の短い構成にしても、第一切断装置３が切断する直前から誘導状態にして保持し、前倒れ状態の茎葉を切断後に挟持して後方の排葉搬送装置５に適確に受け継ぎ搬送を行うことができる。 In addition, as shown in FIG. 15, even if the upper conveying apparatus 36 has a short conveying distance, the upper conveying apparatus 36 is held in a guided state immediately before the first cutting apparatus 3 cuts, and holds the fallen leaves after cutting. As a result, it is possible to accurately carry out the transfer to the rear leaflet transfer device 5.

図１５に示す短い上部搬送装置３６の伝動構成３８は、下側の伝動装置３２から動力取出軸３８ａを、予め装備して上部に着脱部を設けておくと、上部搬送装置３６をアタッチメントとして着脱自由に装備することができる。 The transmission structure 38 of the short upper conveying device 36 shown in FIG. 15 is equipped with a power take-off shaft 38a from the lower transmission device 32 in advance and an attaching / detaching portion is provided on the upper portion, and the upper conveying device 36 is attached / detached as an attachment.

次に、前輪１３，１３、及び後輪１４，１４に関連する実施例を説明する。
まず、前輪１３，１３は、図１６、及び図１７に示すように、基部を車体フレーム４ａ，４ａの中間部位の外側に幅方向のトレッド調節を可能に支持した左右の支持アーム４０，４０の先端部に上下調節自由に挿し通した支持軸４１の下部に軸装した構成としている。 Next, an embodiment related to the front wheels 13 and 13 and the rear wheels 14 and 14 will be described.
First, as shown in FIGS. 16 and 17, the front wheels 13, 13 have left and right support arms 40, 40 that support the tread in the width direction on the outside of the intermediate portion of the vehicle body frames 4 a, 4 a. It is set as the structure mounted in the lower part of the support shaft 41 inserted in the front-end | tip part freely in the up-and-down adjustment.

したがって、前輪１３，１３は、車体４前部の支持構成を廃して、第一切断装置３に近い位置にコンパクトな構成で支持しており、トレッド調節や高さ調節が容易にできる特徴がある。 Therefore, the front wheels 13 and 13 eliminate the support structure of the front part of the vehicle body 4 and are supported in a compact structure at a position close to the first cutting device 3, so that tread adjustment and height adjustment can be easily performed. .

そして、後輪１４，１４は、図１８に示すように、ミッション装置１７からサイドクラッチを経由して取り出される走行動力を、左右のホイルシャフト４３，４３からチエンケース４４，４４を経由して伝動する構成としている。そして、左右のチエンケース４４，４４は、落下してくる切断排葉を避けるために、一対の後輪１４，１４の内側に配置して伝動する構成とするが、図１８に示す実施例では、チエンケース４４の機体外側もしくは機体内側のいずれか一方に車輪１４を取り付けられる構成としている。 Then, as shown in FIG. 18, the rear wheels 14, 14 transmit the traveling power extracted from the transmission device 17 via the side clutch via the left and right wheel shafts 43, 43 via the chain cases 44, 44. It is configured to do. The left and right chain cases 44, 44 are arranged inside the pair of rear wheels 14, 14 for transmission in order to avoid falling cut leaves, but in the embodiment shown in FIG. The wheel 14 is attached to either the outer side or the inner side of the chain case 44.

この構成によって、左右の後輪１４，１４は、図１８に示すように、左右輪共に畝上を走行することができ、機体の水平を保つことができるので、安定した走行ができる。
また、茎葉が後輪１４に落下しにくいため、後輪１４に絡み付いた茎葉を取り除く作業が省略されるので、メンテナンス性が向上する。 With this configuration, as shown in FIG. 18, the left and right rear wheels 14 and 14 can travel on the left and right wheels, and the aircraft can be kept level, so that stable traveling is possible.
In addition, since the foliage is unlikely to fall on the rear wheel 14, the work of removing the foliage entangled with the rear wheel 14 is omitted, so that the maintainability is improved.

そして、ホイルキャップ４５は、図１９、及び図２０に示すように、排葉搬送装置５の排葉側の後輪１４に装着するが、実施例では、車輪１４との隙間が無いように配慮して内側に着脱自由に取り付ける構成としている。 As shown in FIGS. 19 and 20, the wheel cap 45 is attached to the rear wheel 14 on the leaf discharging side of the leaf discharging device 5, but in the embodiment, it is considered that there is no gap with the wheel 14. Thus, it is configured to be freely detachable inside.

したがって、後輪１４は、第二切断装置６によって再度切断されて落下する茎葉の先端部が降り掛かってきても上記ホイルキャップ４５によって絡みつくことが防止できるので、後輪１４に絡み付いた茎葉を取り除く作業が省略されるので、メンテナンス性が向上する。 Accordingly, the rear wheel 14 can be prevented from being entangled by the foil cap 45 even when the tip of the fallen leaf that is cut again by the second cutting device 6 falls, so that the leaf and leaf entangled with the rear wheel 14 is removed. Since work is omitted, maintainability is improved.

そして、車体４には、図２１に示すように、右側のチエンケース４４の後部中間部位にステップ４６を取り付けて、旋回時に作業者が足で踏みながら旋回することができる構成としている。ステップ４６は、右側に配置したから圃場面や溝に切断排葉が落下せず、邪魔にならない。そして、車体４は、旋回時には、サイドクラッチと上記ステップ４６とを併用して、すなわち、右側のサイドクラッチレバー４７を切り操作してサイドクラッチを切り、ステップ４６（右側にある）を踏んで停止させて右側を旋回内側にして旋回することによって、旋回作業にかかる作業者の労力が軽減される。 As shown in FIG. 21, the vehicle body 4 is configured such that a step 46 is attached to the rear middle portion of the right chain case 44 so that the operator can turn while stepping with his / her foot during turning. Since the step 46 is arranged on the right side, the cut leaves are not dropped in the field scene or the groove, and it does not get in the way. When turning, the vehicle body 4 uses the side clutch in combination with the above step 46, that is, the right side clutch lever 47 is turned off to turn off the side clutch, and step 46 (on the right side) is stopped. Thus, by turning the right side inside the turning, the labor of the worker for the turning work is reduced.
